Maximize your KDSS + extended travel shocks

[dom42]

Good stuff, Finally found someone has the same thought!

Dude why did you not make these ? As in for sale and what not ? I would have bought for sure. When I came up with the idea I searched like crazy and found no fix. So I decided to make them. I have my first batch coming soon.

I understand how the ...spacer?... in the rear helps but how does it help in the front? Is there a clearance issue in the front too?

The spacer/pad in the front is an experimental one. I don’t think it is really necessary for a 2” to 3” lift.

Although the front sway bar will be pull up along with the lift, buy since the sway bar arm is longer than the rear, the pulled height is not as much as the rear. Hence I the thickness of the pad in the front is only 1/2 in my solution.

The reason to have the front padding is I want to restore the piston position of the KDSS link back to center, and relief unexpected force like the rear as well.

Here’s the measurement for KDSS link in the rear for reference:

Max length 385mm
Min length 265mm
from the center of sway bar to the center of top screw hole of the KDSS link.

In theory, the length above should be 320mm if the piston position is in the center position. And the length of the rear KDSS link is 325mm approximately, which is perfect to me.

One more thing which I think is quite important. You should check the rubber limiter position of the KDSS link sometimes, especially after off-roads. If that slips, just cut the old stainless straps, reposition the KDSS link to make sure it is vertical and the rubber, and fix it with new straps.

This will help a lot for KDSS/ sway bar effectiveness for on-road driving. If you find that there’s a slip on yours, after restoration, you can feel more stiff and less roll during cornering.

Hello dom42,

That’s why I feel quite happy when I saw your solution. At the time when I designed mine, I need to use 3D scan for perfect matching so that the pad can joint the bottom of KDSS link without any slip in horizontal direction.

For the front one, I only made this for a few team members in our local LC 150 group. PM me if you want to save some time for the front one, but I think it is not a problem for you if you decide to make your own one.

Yes that was one of my concerns. I did notice that when I installed on another buddies truck. He did one side and didn’t put it on correctly and it actually tore. Luckily we have had 2 back ups.

For me the front kdss piston didn’t move down! It’s in the same exact location . [emoji2371]The sway bar just pivoted down( I have 2” inches of lift height). Im working on a piece to get the sway bar arms to the same angle as stock height.

Took some photos for max/min length of KDSS link 10mins ago for reference. This hasn’t reach the maximum articulation yet.

Yes, the piston position of the front KDSS link won’t move that much, but the sway bar arm angle will be changed. Since the sway bar joints with the front axle lower arm with a bracket, instead of an ankle, change in sway bar arm angle will make the joint angle bad, and may introduce unnecessary worn for the bushing. Adding a pad will restore the angle, which helps the issue.

hey so do you have these spacers made? I am installing my lift in the next 2 weeks and this was the exact hypothetical solution i came up with and talked to my shop about. and they told me it didnt exist.

just take my money!! lol

In about 2 weeks I will have a batch for about 100 4runners. Go to my original post. Click the link to my Instagram. Follow me on there for the update as well as the main Instagram account. You will see it in my profile. I don’t want to violate and forum rules but advertising them here with out paying for vendor fees. Fine your way to my website and sign up for the email notification!

So in on this!

I just got the new Dirt King LCAs with the pivoting KDSS bracket. They're supposed to alleviate the strain on the bushing by keeping the proper angle that the bar inserts into the bushing.

This new pad looks to be a cheaper way to solve that problem, although I am enjoying the ride of the new LCAs.

if you are trying to patent this, delete this thread and anywhere else you have published this. get other lawyers if this is the advice they gave you.

This idea has been out there for quite a while. I think it's been built before as well. Let me find some old posts.

Here's an old drawing from ~2016.

So I think that ship sailed a while ago.

But it's cool that someone is trying it. I have a problem with bending my rear link already (the fixed side looks like a banana) so dropping it another inch or two would make it more of a problem in the rocks. The front would be a problem with skid plate interference. And the front would be easier to put a spacer plate on the KDSS mount on the control arm to raise that point an inch or so.

Good luck with the product though! I think it could help a lot for a lot of folks.

So do you know who built them? Or did the idea just stop ? I seen one guy in here who did it for himself.

I search like no other. Guess I didn’t dig deep enough. But before even searching I came up with this in my head and like I always do , I don’t hesitate to make things happen.

If this was out already I totally would have just bought it instead of making it.

Pictures of those puppies??? I haven’t seen anybody run those yet.

Dom, where are you located? It will be nice to find a solid solution for the passenger side lean.

Really need a video of the suspension cycling to see the pivoting bracket in action.

I’m in SoCal. Norco Corona area.

This spacer isn’t to correct the lean. It’s for maximum droop for with kdss 4Runner.

Not saying it can’t or that I don’t have an idea about how to fix it using this method but there’s better ways to do it. I personally wouldn’t rely fixing other with this sway bar drop.

I don't know who did this first. I remember seeing the idea come up multiple times in the 5 or so year's I've been paying attention. Generally the same solution has come up most times. It's easy to make and the obvious solution as an alternative to relocating the piston mount on the frame side or moving the brackets on the lower control arms up front and the rear axle. I think you might be the first to actually sell them commercially if you do sell them.

The general reason that they were not pursued was that the travel range of the suspension in the front isn't changing with a lift and the OEM system can cycle through the entire range of travel already. So lowering the sway bar to a different static position probably doesn't actually do much good and ends up causing interference with skid plates.

The rear does appear to help quite a bit with clearance of the track bar. I think most people chose to relocate the track bar bracket an inch or two higher as an alternative because it also fixes the geometry problem with an unlevel track bar. I do think this solution works great in the rear for a situation where you want a bolt on solution that's easy to reverse and you're not going rock crawling where you'll be dragging the rear sway bar on the rocks. That probably encompasses most lifted 4Runners. I suspect a fair amount of folks would probably use them.
